Gents—PHILOSCIA Latreille, 1804 (37), p. 43. 
Flagellum with three joints; abdomen narrow; head without 
lateral lobes. 
If any further differences of an obvious kind be required to 
distinguish Philoscra from Oniscus, one at least will be found in 
the much greater development of the hinder legs in the former 
genus.

This species lives chiefly at the roots of grass and under the 
stones or sticks that lie among it. Philoseia 
muscovumt has a very smooth and shining body, 
and its long legs enable it to move very rapidly. 
The ground colour of its dorsal surface varies 
from light yellow to deep brown. There are 
characteristic dark markings down the middle 
of the thorax and on the sides, between which 
are lighter patches. In dark coloured speci- 
mens the markings are by no means so evident.
